18 Cryptococcus-associated immune reconstitution inflammatory syndrome (C-IRIS) is identified upon immune reconstitution in immunocompromised patients, who have previously contracted an infection of Cryptococcus neoformans (Cn). C-IRIS can be lethal but how the immune system triggers life-threatening outcomes in patients is still poorly understood. 9/30/2015 1/30/2019 1/17/2017 5/8/2007 1/21/2020 9/29/2020 {{configCtrl2.info.metaDescription}} Cryptococcus is a common opportunistic fungal pathogen in human immunodefi ciency virus (HIV)-infected individuals with advanced immunodefi ciency, usually manifesting as cryptococcal meningitis.

There are limited data on managing cryptococcal-associated IRIS. We describe an immunocompetent patient who developed IRIS complicating Cryptococcus neoformans meningitis, successfully treated with thalidomide following failure of Although ART dramatically reduces HIV-associated mortality and improves patient outcomes, initiation of or a change in ART introduces the potential for IRIS.

Here, we establish a mouse model for C-IRIS with IRIS associated with Cryptococcus was modelled in the mouse successfully, in which RAG −/− mice were infected with C. neoformans and transferred with CD4 + T-cells after 4 weeks. The data show the development of multiorgan immune reconstitution disease and systemic increases in the pro-inflammatory cytokines IFN-γ, IL-6 and TNF-α [ 58 ]. IRIS consisted of acute symptoms consistent with inflammation occurring within a median of 8 months (range, 2-37) after the diagnosis of cryptococcosis in the context of negative cultures and immunological and/or virological response to HAART.
